Touchscreen Installation
1. Clean the reverse side of the replacement touchscreen with the supplied alcohol wipe.

screen without overlapping. After the tape is in place on the screen, peel off the backing.
3. Replace the new touchscreen over the monitor in the same manner as the old screen, making
sure the screen is properly and evenly aligned over the monitor glass. Then clean the front of the
screen with the supplied alcohol wipe.
4. Carefully slide the new monitor into the bezel, making certain that the white edge of the monitor
and the monitor wire connections are facing the bottom of the bezel. Ensure that the monitor is
properly centered, then tighten the hinge screws. See Figure 2.
NOTE: If you removed the joystick on your Elite Edge, carefully return the game to its side and
reconnect the joystick to the connector in the game. Place the protective bracket in its previous

stalled screws. Make sure all wires are secured inside the bracket, then reinstall the 2 screws
securing the bracket. Return the game to its upright position.
